Sinumerik Alarm 6560 Data format not allowed
An attempt was made to write impermissible data in an NCK file. This error can occur in particular when the attempt was made to load binary data in the NCK as ASCII file. The error can also occur during preprocessing of cycles (see $MN_PREPROCESSING_LEVEL) if the NC block is very long. In this case, subdivide the NC block.
– Alarm display.
Specify that the file concerned is a binary file (e.g. extension: .BIN).
Clear alarm with the Delete key or NC START.
